does making a blog increases our earnings?

The simple answer is yes a blog can increase your earnings. Now the more complex answer. Although setting up a blog is extremely easy it is not a case of build it and wait for the money to come rolling in. To really capitalize on having a blog you need to work at it nearly on a daily basis, especially for the first few months. You need to build up a lot of useful, orginal, quality content which visitors will stay and read. You need to keep adding to it on a regular basis and also fine tune existing pages on your blog. Plus you have to market it so that people know it exists. Plus you can't expect to make much money from it for quite a while after you launch it as it takes time to build up a decent amount of traffic. If you have the time, patience, determination and a long term vision to making money then a blog is a good way to go.
